I tried to purchase a gun this past Thursday at Walmart (I know... but it was a clearance model, great deal!) and according to the cashier/dept. manager I must have answered a question wrong on the 4473 form because she said I was denied or blocked and could not proceed. My Gwcl was presented so I am fairly certain it wasn't a background check issue. I didn't think too much of it and tried to purchase a different clearance gun at a different Walmart yesterday and after the form was submitted the salesperson said I was on a block list and couldn't proceed. Has anyone else experienced this and if so where do I start to resolve the issue?
